The objects of these improvements is to simplify the construction of thelock itself,

the manner of securing the back in place and, to reduce the cost ofconstruction without affecting the durability of the lock.

With these objects in view, the invention consi-sts of the novelfeatures of construction hereinafter fully described, pointed out in y'the claims, and shown in the accompanying drawings, in which, y

Figure 1 is a face view. Fig. 2 is a vertical section. Fig. 3 is asection on the line 3 3 of Fig. 2. Fig. 4 is a section on the line 4 4 oFig. 2. Fig. 5 is a perspective view of one of the rings. Fig. 6 is adetail sectional view 4showing in plane portions of the inner faces offlanges carried by certain rings.

In these drawings, 1 represents a cylindrical casing which at its frontis provided with a rabbeted flange 2, within which rotates a dial plate3, provided with a suitable notch or mark 4 and the outer face of theflange 2 is .provided with a suitable scale 5. The

-dial plate is provided with a milled head 6 by mean-s of which it canbe readily turned. A back plate 7 lits over the rear end of the casing 1and is provided with an annular flange 8, which fits within the casing 1and bears against the inner face of the flange 2. A shackle 9, the freeendV portion of which is provided with oblique grooves 10, upon itsopposite sides, is constructed and mounted the same as the shackleshownin my previous patent. This shackle is adapted to be lifted 'verticallya certain distance, then to be swung to oneside. The flange 8 is slot,-ted as shown at 11 to permit said shackle to pass therethrough, thecasing l'of course having a suitable slot 1*:L for this purpose. Theback plate is locked in position by means of a bayonet slot 12, cut inthe flange 8, which vslot engages a pin 13,.carried by the casing 1.Thls greatly simplifies the securing of the back plate in position. overthe construction shown in my previous patent.

Placed within the casing are two rings 14 and 14, said rings beingrecessed or cutaway as shown at 15, and when saidrings are turned inorder to bring said recesses into alinement with eachother a circularopening is formed vthrough which the lfree end of the shackle can pass,provided of course the rings are also turned into such position that theopening? so'formed by the recess 15 will register with the openings 1ELWhen the end of the shackle is passed through said openings, the ringscan then be turned so as to cause them to travel in the grooves 10,respectively, thus locking the shackle within thel casing. Each ring isprovided with an' interior flange 16, and on said ilanges are formedsuitable teeth 17, the depthbf said teeth beingless than that of theflanges. FittingV within the rings and resting upon said'flanges andmeshing with the teeth lare toothed wheels 18 and 19, and said wheelscarry pins 2O and 21, so situated that upon rotation of said wheels onepin will 'engage the other.

The wheel 18 is secured in place by a suitable screw 22 and the wheel 19receives a suitable stub shaft -24 formed on the back plate -7 andprovided with aI threaded portion upon which is fixed a4 suitable nut23.

It will be obvious that by turning the dial 3, the wheel 18 willlbeturned 'and this in turnwill rotate the ring 14. When the pin 20 picksup the pin 21, the wheel 1 9 and the ring 14a will be turned, the backplate however remaining stationary as the wheel 19 turns loosely uponthestub shaft 24 carried by said back plate.

The wheels 18 and 19 are readily detachable from their respective rings,and by detaching them or any one of them and reinserting the same'within the ring with the pin or pins occupying a different relativeposition with res ect to each other changes vca'n'be made in t ecombination.

What I claim is:

f1. A lock of the kind desm'bed mapas-y ing a casing having aninteriorllan e adjacent its front, said flange being rab ted, a dialplate turning within said flange and bearing thereupon, a back plateadapted to close the inner end of the casing and having an lannularflange adapted to twithin the casing and to bear against the firstmenback plate, avtoothed wheel turning loosely upon said stub shaft, aflanged ring mount- Correction in Letters Patent No.1,058,861.

ed upon said toothed wheel and turning therewith-.said ring beingnotched, a similar Wheel 'x'ed upon the inner face of the dial plate, aflanged and notched ring mounted on and ,tlifmng with said lastmentioned wheel, pins carried by said wheels and adapted to engage eachother, a shackle adapted to pass through the opening formed by theregisteringv of the ring notches, said shackle being grooved uponopposite sides to receive the rings, and means for locking said backplate in posit-ion, said plate being removable when the shackle isWithdrawn rvfrom the lock.

[siiAL] adapted to pass through said openings and means arranged Withinsaid flange 4 locking said shackle against Withdrawal.
